Abstract
A technique for creating an image onto a photosensitive medium in a photoprinting process involves scanning a phototransparency for its densitometric information. Light from a lamp source is transmitted through an LCD pad onto a photosensitive medium to produce an image. The exposure of the image is regionally varied to achieve optimum results by activating individual LCD pixels to control the amount of light exposed to the photosensitive medium. A microprocessor calculates the activation pattern for the pixels based upon the densitometric information of the phototransparency.
